Bill Meyer (Chicago Reader): "...the impeccable logic of his lines and the richness of his tone leave you wanting more... Jackson's high-register squiggles and coarsely voiced, rippling runs push the limits of the tenor's tonal envelope."
Frank van Herk, de Volkskrant (Amsterdam): “[Jackson] has an old-fashioned, warm-woolly sound, and a feeling for melodic lines that take their time in unfolding." He has been mentioned in the DownBeat Critics Poll in the Rising Star Tenor Saxophone category. Recordings are available on Delmark and Clean Feed Records.
